SingleLineThrowFixer - fix handling anonymous classes

[kubawerlos]

Is this a right solution or SingleLineThrowFixer should not remove new lines from anonymous class definition?

Ping @nicolas-grekas for an opinion (as you are the person who originally requested this fixer).

I can't review the logic as I'm not into php-cs-fixer much but I think the target is nice, thanks for working on this!

@nicolas-grekas I am interested on your opinion from a user perspective - what should happen to this code:

throw
    new class()
        extends Exception
        {
            protected $message = "Custom message";
        }
     ;

Fully single line:

throw new class() extends Exception { protected $message = "Custom message"; };

or without class body:

throw new class() extends Exception
        {
            protected $message = "Custom message";
        };

?

it can be pretty long
can we, easily, achieve that throw new class() extends Exception is enforced to be a single line, and the body of class is formatted properly by braces fixer?
if not, let's skill formatting of anonymous classes by single_line_throw, imho

Thank you @kubawerlos.
